Answer:
600
Step-by-step explanation:
The common multiples from the multiples of 15, 25, 40, and 75 are 600 and 1200, but the smallest common multiple of 15, 25, 40, and 75 is 600.
Answer:
C
Step-by-step explanation:
Like terms are terms which have variables that sound a like and look a like. 
has both the variables u and v with an exponent of 2 on the u. Only C and D have these characteristics. It's not D since v also has an exponent. C is the solution.
Answer:
C=13 cm
Step-by-step explanation:
So the larger number is x, and the smaller number is y
7y=x
3x=7+4y
(So plug in the 7y=x information into the second equation)
3(7y)=7+4y
21y=7+4y
17y=7
y=7/17
The height of the mountain is 0. 2 km
<h3>How to determine the height</h3>
First, let's find the hypotenuse of the second triangle
Using the tangent identity, we have;
tan θ = opposite/ adjacent
tan 3. 5 = x/ 19
cross multiply
x = tan 3 . 5 × 19
x = 0. 061 × 19
x = 1. 16 km
Now, we have the hypotenuse side of the second triangle and we need to find the opposite side which is the height of the mountain
Using the sine identity:
sin 9 = y/ 1.16
cross multiply
y = sin 9 × 1. 16
y = 0. 1564 × 1. 16
y = 0. 18 km
y = 0. 2 km in one decimal place
Thus, the height of the mountain is 0. 2 km
